Hi! I've made bbCode extension plugin for my bbcode plugin to use embed.ly service easily.
To install do npm i nodebb-plugin-bbcodes-embedly
You can setup plugin in admin panel (image)
@JonDoe12 It's doable, you'd just take someone entering [font=8]text[/font] and replace the font bits with some css. maybe via span classes or something like that.
That, I haven't seen a plugin for, but I don't see why somebody couldn't make that a plugin...
